Precautions for steel structure installation:
1. During installation, it is necessary to ensure that the main foundation of the center is parallel to the plant building, and the promotion of the batching system should be well connected.
2. Calculation method of stair cutting size: calculated by horizontal height, horizontal length and channel steel model.
3. When installing decorative columns, first set the straight plane and then hang the angle circle beam to ensure accuracy and stability.
Key points of on-site process layout verification:
1. It is necessary to strictly measure the size of the drawing and the actual size of the site to ensure the accuracy of installation.
2. Concrete strength requirements: the ground needs to meet the C15 standard, and the foundation columns need to meet the C30 standard.
3. The allowable range of position deviation of embedded parts: plus or minus five elevations are plus or minus three millimeters.
Key points of comparison between steel structure and drawings
1. The design position of the temperature measurement point and the ring beam column should be checked to avoid space conflict and the equipment cannot be installed.
2. The main and secondary beams of the platform should be checked for conflicts to avoid installation difficulties.
3. The electrode installation position should be checked for conflict with columns, joists and main and secondary beams to avoid affecting the electrode work and the bearing capacity of the steel structure.

The physical and chemical properties and characteristics of alkaline slag glass liquid such as erosion resistance, impedance, thermal stability, mechanical strength, bulk density and shrinkage. Among them, the glass liquid performs prominently in the reducing atmosphere and can effectively block metal drilling; low expansion coefficient and good thermal shock stability; After high temperature sintering, a dense structure is formed, with an internal compressive strength of up to 10-12 megapascals and a compressive strength of up to 64-70 megapascals. In addition, the configuration of capacitive high steel jade guide feeding, including inverted feeding, sealing material and mud, as well as the configuration method of binder, is also introduced.

Advantages and disadvantages of different height powder layers
1. Advantages and disadvantages of powder layer thickness Taking conventional soda-calcium wine bottle products as an example, under normal circumstances, the height of the powder layer is controlled at 200~300mm, and the production effect is the best. If the height of the powder layer exceeds this range, it is easy to cause uneven material, that is,
Characteristics of the powder layer of the glass electric melting furnace
The batch layer covered on the surface of the electric melting furnace is called the powder layer, and the height of the powder layer is an important parameter for the design of the glass electric melting furnace. Different from the traditional flame kiln, the electric furnace adopts a vertical melting process, and the powder layer is completely covered on the surface of the molten glass in the melting pool, and at the same time, the heat radiation of the melt to the kiln roof is blocked, so that the temperature of the upper space of the kiln is reduced to below 150 degrees Celsius, commonly known as "cold top". The volatile components in the batch are condensed in the powder layer and flow back into the molten glass, and gases such as carbon dioxide released during the melting process can easily pass through the powder layer and enter the space. The powder layer flows from top to bottom and melts continuously as the temperature rises, gradually completing the clarification and homogenization process.
Structural reinforcement and design recommendations for the breast wall Problems in the design and reinforcement of the breast wall structure. It is recommended to consider tiling and supporting structures in the design to avoid voids and deformations. At the same time, on-site construction can also be carried out according to the actual situation, and various materials and methods can be used for reinforcement. In addition, the problem that the exposed steel bricks in the oven process are not affixed with thermal insulation paper leads to serious explosions, which reminds everyone to pay attention to this problem and avoid similar situations.
On-site treatment of cover brick tilting problem and problem analysis
Measures to deal with the problem of tilting of cover bricks The top wire of the cover of an electric furnace built by our company is movable and can be twisted by hand. The reason is that the open-hearth furnace is not adjusted in time when it is kept warm and resumed production, which causes the lower pool wall or the top wire of the pool wall to shrink and the gap to become larger when the furnace is stopped. When the temperature rises, the gap becomes larger, and the bricks will go outward, causing them to sink. In order to solve this problem, a wire position can be welded between the supporting plate and the column to make the supporting plate fixed. In addition, the lack of power of the flowing fans, resulting in large temperature differences, may also be one of the reasons. Finally, the cover bricks and the fused bricks between the over-layer are not reinforced and also need to be strengthened.
